Have Gone Down The IVF Path To Have Kids? Here’s What You Need To Know
Last Updated:
If you are struggling to have kids via IVF, an expert breaks down why it might not be working.
Younger patients generally have higher success per IVF cycle.
For many young couples who want to have a baby, IVF feels like a miracle ticket. However, it is important to realise that it is not a guarantee. Many couples are faced with unexpected roadblocks during their pregnancy and IVF journey. Understanding the biology and realistic limits of this procedure can help families make clearer, less painful decisions as they go down this route.
We speak to Dr Santosh Gupta, Clinical Director & Fertility Specialist, Nova IVF Fertility, Koramangala, Bengaluru, to understand when one knows the right time to stop IVF treatments and look at other options to have a child:
When IVF “fails,” in most cases, this implies either failed implantation of the embryo or loss of early pregnancy by miscarriage. Indeed, the process of implantation is rather complex, as only a healthy embryo needs to be introduced at the precise time to the receptive endometrium, and, in fact, both of these need to be healthy as well. Factors such as low quality of the embryo (related to egg age), timing, any pathology in the uterus, immunological or infection problems, and environmental factors might disrupt this complex process.
Egg quality — the single biggest biological limiter
Egg quality declines with age because of chromosomal errors. That’s why younger patients generally have higher success per IVF cycle. The number of eggs retrieved also matters: more good eggs increase the chance of one embryo that will implant and carry to term. Recent prediction models and cohort studies show age-specific thresholds where the probability of live birth drops sharply, making age the dominant predictor that clinicians use when counselling patients.
Some common culprits
Factors affecting uterine difficulties are polyps, fibroids, adhesions, blood flow problems, blood clotting problems, immune system problems, and inconsistent hormonal patterns. Environmental factors include air pollutants affecting eggs, as shown in recently emerging studies on systemic inflammation affecting egg quality and success rates of IVF.
Treatments help, but there are limits
Modern medicine has a number of fixatives: improved embryo selection (like genetic screening), skillful lab work, hysteroscopy to remove any issues in the uterus, or directed medical attention for clotting or hormonal troubles. In cases involving pituitary or ovarian function, directed medical attention is available. Nevertheless, many cycles fail to produce a live-born child at even the most successful fertility centres.
When should you stop? It’s a decision, not a rule
There’s no single “stop here” button that fits everyone. But several practical rules guide specialists:
• Age matters most. Outcomes fall steeply after the late 30s; after about 45, autologous (your own eggs) IVF is widely considered futile or of extremely low probability, and many experts discourage further cycles. Decisions change if donor eggs are an option.
• Ovarian reserve and egg yield. If repeated cycles produce very few eggs or poor-quality embryos, the incremental benefit of more cycles is low. New models can estimate cumulative live-birth chances based on age and egg numbers — use these to guide realistic planning.
• Repeated failure despite “good” embryos. If you’ve transferred multiple good embryos over several cycles with no pregnancy (some definitions use three cycles or four good embryos), clinicians invoke the concept of recurrent implantation failure and start deeper investigations; sometimes a different strategy or a pause is wiser.
• Emotional, financial and health costs. If treatment is causing harm — severe stress, relationship breakdown, depleted finances, or medical risks — stepping back is a valid, often healthy, choice. Ethics guidance urges clinicians to discuss futility and limits openly rather than push endlessly.
How to make this call — a practical checklist
• You may ask your clinic for your overall live birth probability given your age and egg supply.
• Assessment of cycle logs: Embryo Grades, Genetics Results (if performed), Uterine Evaluation.
• Reflect on if any modifiable risk factors (such as smoking, weight, air pollution exposure) have been
• Seek a second opinion if a possibility was not explored.
• Establish what your end criteria are: what makes you or your partner want to stop trying to get pregnant? Discuss this with your doctor and agree upon it.
IVF can achieve remarkable results, but it has biological limits. The smartest approach mixes science with honest conversations about probability, cost, and well-being. That way, families can choose hope without losing sight of reality.
